WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 245,319, dated August9, 1881.

Application filed April 6, 1881. (ModeL) T 0 all whom it may concern:

Be it known that I, JOHN ROBERTSON, of Montreal, in the Dominion ofCanada, have invented an Improvement in Water-Closets, of which thefollowing is a specification.

Figure 1 is a vertical central section of the trunk of a water-closetcontaining my invention. Fig. 2 is a perspective view of the same. Fig.Sisa detail horizontal sectional view, showing the valve for closing thedischarge-orifice in two positions. Fig. 4 is an enlarged sectional Viewof said valve and ot the packing against which it bears. Fig. 5 is adetail top view, partly in section, of the mechanism for operating thevalve and of the trip mechanism for opening the water-supply. Figs. 6and 7 are detail side views of the mechanism for actuatin g the trip.

This invent-ion relates to a new construction and arrangement of valvefor closing the outlet-orifice of a water-closet, and to the novelmechanism for actuating it, to a new arrangement of water-passage forsupplying and washing the closet, and to new trip mechanism foradmitting the water to the pan of the closet, all as hereinafter morefully described.

The invention consists in the use of a swinging and also vibratory valveor disk, which closes against an inclined packing in the lower chamberof the closet below the trunk, and:

thus insures the proper and tight closing of the closet and prevents theascent of gases.

The invention also consists in the new mechanism for conveniently movingthis valve and for adjusting it so as to regulate its pressure againstthe packing as the latter may become worn in use, and in other detailsof improvement which I shall hereinafter fully describe. In thedrawings, the letter A represents the suitable bowl or basin of thecloset, and B is the chamber into which this bowl or basin discharges,and on which it rests. This chamber is preferably ofinverted truncatedconical form,

and has a flange, a, at its lower part, which rests upon the flange ofthe packing O, confining it between the chamber B and the lower chamber,D, of the closet. The flangeais bolted or otherwise properly secured tothe chamber D, so as to insure also the proper retention of the packing.This packing is inclined on its lower face and oblique to thefiange a,be

ing so formed that it extends farthest down at the place which isfarthest distant from the pivot b of the valve E, that closes againstthe packing, as clearly shownin Fig.1. The valve E is a circular diskwith a downwardly-projecting central stem, d, that passes looselythrough an eye in the end of a link,jib, or

crank, 6. This link or crank is rigidly secured to the stem or verticalpivot-pin b, and by turning this pin I) the valve or disk E will becarried either beneath the packing, as shown in Fig. 1, which is theposition shown by full lines in Fig. 3, and as shown also in Fig. 4, orinto the extension D of the chamber D, as shown by dotted lines in Fig.3. When under the inclined packing the disk or valve E is by frictionalcontact tilted into the inclined position on the packing,which is shownin Fig. 4, and thus makes a tight joint, so as to prevent the escape ofgases in an upward direction. If thepacking 0 should wear, the valvewill always accommodate itself to the wear, owing to this tiltingaction; and, moreover, it can be adjusted up and down 'by setting thepin 1) farther up or down in its bearings, or adj ustingthe arm 0 onsaid pin.

The chamber D D has asliding gate, y, Fig. 3, which, when opened, admitsready access to thinterior ot' the chamber and to the valvedisk E.

The pin 1) vhas a moving crank,f, which is more fully shown in Fig. 5,and which connects by a link, g, (see Fig. 2,) with an elbow-lever, F,to which the draw-handle G is attached. By pulling on G the link 9 ispulled in the direction of the arrow shown in .Fi g. 5, and thecrank-pin I) turned so as to carry the valve E out of the way of theoutlet from the closet.

As soon as the handle G is let go a suitable weight, t, or spring bringsthe parts back to their normal position, which is shown in Figs. 1 and4.

Thelever-F has also a projecting arm, j, with a pin, k, at the endthereof, and when this lever F is vibrated by pulling the arm G so as todischarge the contents of the closet the pin it is carried upon thecrankprojection lof a rockshaft, H, which is shown in Fig. 2. Therockshaft H has another crank, m, that connects by suitable rod or wire,a, with the lever I of the water supply cistern, and the shaft H has astill further crank, 0, which carries a weight,

2. The tendency of this weight 1) is to hold the trip-crank Z in thehorizontal position and to hold the rod it down. hen, on pulling 5handle G, the pin k strikes the trip-crank l and the lip 0', thatprojects therefrom, (see Fig. 6,) it at first tilts the crank l downwarduntil the pin 1 has reached the inner edge of the lip 1', which is aboutthe position shown in Fig. 6. Just as the pin 1 has passed this inneredge of the lip r the weight 2 becomes operative and carries the crank Iimmediately back toits h orizontal position and draws on the rod n. Now,as the weight 1', after the handle G is let go, exerts its i n fluencethe pin kascends and reaches the under side of the lip 1', as in Fig. 7,and begins to draw farther on the rod n, so as to move the lever Isuflicient to open the valve that admits water to the pipe L, with whichthe closet-pan is washed. This movement leaves the trip motion free.Thus, by means of the mechanism shown, and particularly by thearrangement of the pin it and lip 'r in their corelation with theweight 1) in the manner shown, admission of water is made part of theoperation of the link mechanism, and made to be effective as the disk Eresumes its proper position under the packing G. The water that isadmitted to the basin A washes the same in the usual manner and has itsoutlet through a pipe, 8, that starts from the upper portion of thechamber B, as shown in Fig. 1. This pipe 8, by means of partitions t, u,and o, is made to first ascend, then descend, then ascend, and, finally,again descend nntilit reaches the portion D of the chamber 1), whencethere is a free outlet for the water to the wastepipe below the valve E,and yet, by means of the partition u and the other partitions mentioned,a complete double seal of water is insured and obtained, and the escapeof gases in an upward direction from the chamber D elfectuallyprevented. When the valve is opened all the contents of the pan A andchamber B rushdirectly down into the waste-pipe, but whenever the valveis reclosed and water readmitted the water rushes in until the level isequal to the upper edge of the partition 2.

The upper end of the pipe 8 has a small airhole, 10, which supplies airbetween the two traps at the time the water flows downward from the pipe.9 into the chamber 13, which is the case as soon as the valve E isopened.

I claim 1. In a water-closet, the combination of the swinging valve Ewith the vibrating carryingarm e, and with the annular packing O, havinginclined lower face, all arranged so that the valve will be tilted onthe arm e and wedged between the inclined seat and on the arm 0 whencarried beneath the seat, substantially as herein shown and described.

2. The combination of the swinging valve E, which is capable ofvibrating on its stem (1, with the pin 0, having cranks or jibs e and f,link g, and weighted operating-lever F, substantially as herein shownand described.

3. The chamber B, made with flange a, in combination with the packing O,forming a valve-seatthatisobliquetothelineoftheflange a, with thechamber D, having extension D and with the valve E, all arrangedsubstantially as specified.

4. In a water-closet havinga vibrating valve, E, which is adapted toclose under the annular packing G, which is beneath the pan A, thecombination of the intermediate chamber, B, with the pipe 8 andpartitions t u 11, all arranged so that there is a continuous passagebetween the chamber B and the branch or extension D and the soil-pipe,and so, also, that the water must seal said pipe 8 whenever the valve Eis properly closed, substantially as herein shown and described.

5. The combination of the lever j, having pin k, with the rock-shaft H,having crankl and lip '1' thereon, and with the weighted crank 0, allarranged so that by vibrating the leverj the shaft H will first berocked in one direction and then in the opposite direction,substantially as herein shown and described.

JOHN ROBERTSON.
